[11][12] The Coca-Cola Company and other U.S. soft drink makers continue to use sugar in other countries but transitioned to high-fructose corn syrup for U.S. markets in 1980 before completely switching over in 1984.

[13] The Coca-Cola Company originally imported the Mexican-produced version into the U.S. primarily to sell it to Mexican immigrants who grew up with that formula.

[2] Mexican Coke was first sold at grocers who served Latino clientele, but as its popularity grew among non-Latinos, by 2009 larger chains like Costco, Sam's Club and Kroger began to stock it.

[14] A 2012 scientific analysis of Mexican Coke[15] found no sucrose (standard sugar), but instead found total fructose and glucose levels similar to other soft drinks sweetened with high-fructose corn syrup, though in different ratios,[5] but a response to that study said that sucrose hydrolises to its components in acid environments very fast.

[21] A similar phenomenon exists in New Zealand, where Coca-Cola is available both bottled locally (sweetened with cane sugar) and imported from the United States (with high-fructose corn syrup).
